Patient-reported symptoms and interest in symptom monitoring in HCC treated with locoregional therapies: A qualitative study

Background: Patient-reported outcomes (PRO) measures relevant to domains most important to patients with HCC who received locoregional therapies are needed to advance patient-centered research. Furthermore, electronic PRO monitoring in clinical care has been shown to reduce hospitalizations and deaths in patients with other cancers. We conducted a qualitative study among patients with HCC who recently received locoregional therapies to (1) identify common and distressing posttreatment symptoms to prioritize PRO domain selection and (2) gauge interest in an electronic PRO symptom monitoring system. Methods: We performed semi-structured telephone interviews among adult patients who received locoregional therapies (median of 26 days after treatment) for treatment-naïve HCC at a single tertiary care center. Interviews were conducted until thematic saturation was reached. Qualitative content analysis was conducted to identify emerging themes and sub-themes. Results: Ten of 26 patients (38%) reported at least 1 symptom before treatment. In contrast, all participants (n = 26) with recently treated HCC reported at least 1 posttreatment physical symptom, with the most common being appetite loss (73%), fatigue (58%), abdominal pain (46%), and nausea (35%). Most participants (77%) stated they saw potential benefits in posttreatment ePRO symptom monitoring. Conclusions: Posttreatment symptoms after HCC locoregional therapies are common and often severe. These data can inform and prioritize PRO domain selection. Patients are interested in ePRO monitoring to monitor and proactively address posttreatment symptoms. Given the clinical benefits in patients with metastatic cancers, ePRO monitoring warrants investigation in patients with HCC.


INTRODUCTION
HCC is expected to become the third leading cause of cancer-related death in the United States by 2035. [1,2][5] Patients with liver-localized, unresectable HCC may be candidates for locoregional therapies (LRTs), including thermal ablation, transarterial chemoembolization (TACE), transarterial radioembolization (TARE), and stereotactic body radiation therapy (SBRT).With few exceptions, LRTs are not curative-intent procedures, meaning they do not result in life expectancy similar to those without HCC. [6]atient-reported outcomes (PROs) that assess patients' experiences with cancer and cirrhosis treatments are increasingly being identified as important endpoints by patients, clinicians, and regulators, [7][8][9][10][11][12] yet little is known about patients' posttreatment experiences and symptoms for patients with HCC following LRT.A better understanding of posttreatment symptoms after LRTs is needed to inform the selection of PROs most relevant for this population.Once selected, PROs can be incorporated into patient-centered outcomes research and enhance clinical care by informing patients, caregivers, and clinicians of treatment decisions and preparing patients for post-LRT recovery.
There is a growing literature on the role of PROs in HCC.A recent scoping review identified several physical symptoms that were identified through prior qualitative work. [12]A number of PRO domains were identified in this work, including physical symptoms such as body pain, gastrointestinal symptoms (abdominal pain, bloating, diarrhea, anorexia), fatigue, jaundice, rash, vertigo, weakness, and dizziness. [12]Additionally, a multinational survey reported that side effects related to HCC treatments are common, including > 60% reporting abdominal pain and fatigue, 60% reporting absenteeism from work, 37% with inability to carry out daily activities, and 28% experiencing negative impacts on relationships with family/caregivers. [13]ccumulating evidence on the use of PROs also exists in cancer care [14] and, recently, the PRO-TECT trial, a multicenter randomized trial, demonstrated that electronic PRO monitoring among patients with metastatic cancer improved patient-reported physical function, symptom control, and HRQOL. [15]A published single-center trial demonstrated significantly improved overall survival rates in the PRO monitoring group (31 mo) compared to the usual care arm (26 mo). [16]ymptom monitoring with PROs may be particularly important in people with cirrhosis and HCC, given that underlying cirrhosis is present in 80%-90% of individuals diagnosed with HCC.Patients with cirrhosis experience a high baseline rate of acute care utilization that could be exacerbated by LRT for those with concurrent HCC.[21][22] Furthermore, no studies to date have explored patients' interest in a remote PRO monitoring system to proactively evaluate and respond to post-LRT symptoms.
Therefore, we conducted a qualitative study using semi-structured individual interviews with adult patients who had recently undergone LRT for HCC.The current analysis aimed to (1) identify common and distressing posttreatment symptoms in patients' own words and (2)  gauge patient interest in an electronic PRO symptom monitoring system.

Study design
This was a single-center qualitative study using a narrative research approach.Qualitative interviews and analyses were carried out by the University of North Carolina (UNC) Connected Health Applications and Interventions (CHAI) Core, an NIH-funded core that conducts qualitative research and e-health intervention development.The investigative team was comprised of physicians in the fields of hepatology, oncology, interventional radiology, radiation oncology and transplant surgery, qualitative research experts, and experienced qualitative analysts.All research was conducted in accordance with the Declarations of Helsinki and Istanbul, institutional review board approval was provided by the UNC institutional review board (#20-2840), and patients provided written consent before the initiation of any study procedures.

Study sample
Inclusion criteria were: age ≥ 18 years, HCC diagnosis based on American Association for the Study of Liver Diseases criteria, [23] plan to receive thermal ablation, TACE, TARE or SBRT, and English-speaking.We excluded patients who were receiving re-treatment of a previously treated lesion, given that this may affect posttreatment symptoms.Patients were identified through multidisciplinary tumor board and HCC clinics, including the multidisciplinary HCC clinic.Attempts were made to enroll all consecutive patients identified who met inclusion/exclusion criteria.Participants were interviewed 2-6 weeks after receiving or, in the case of SBRT (which requires multiple treatments over several days), starting LRT.

Data collection procedures
A total of 26 in-depth interviews were conducted between September 2021 and August 2022.Enrollment was stopped when thematic saturation was achieved.The interviews were conducted by 3 trained qualitative researchers who are part of the CHAI Qualitative Research Group, which is a shared-resource core for the UNC Lineberger Comprehensive Cancer Center.The CHAI Qual Group works with a wide range of different clinical investigators across a variety of oncologic departments (eg, current projects include kidney, bladder, liver, lung, breast, testicular, and pancreatic cancers).The CHAI Qualitative Research Group are experts on the technical and methodological aspects of qualitative research and collaborate on funded projects with investigators who are experts in the topical or content areas in which they practice.
Interviews were completed over the telephone, lasted ~45-60 minutes, and were digitally recorded.The interviewers followed an interactive, semi-structured interview guide (Appendix A in Supplemental Materials, http://links.lww.com/HC9/A644).The interview guide was developed in a collaborative manner between the investigators and the qualitative experts at CHAI Core.The interview guide was pilot-tested among the qualitative interviewers but not formally tested with patients with HCC prior to data collection.However, iterative changes were made to the semi-structured interview guide based on interviewer experience and feedback during the first few interviews.Participants received a $50 gift card for completing the interview.

Data analysis
All interviews were recorded, transcribed, and deidentified.Interview transcripts were imported into Dedoose version 9.0.86 (Los Angeles, CA, www.dedoose.com.We developed a codebook based on the research questions and notes taken during data collection.The initial codebook was pilot-tested by 4 qualitative researchers who independently coded transcripts, which led to the fine-tuning of coding definitions and revising decision rules on when to apply codes.Emerging themes and discrepancies were captured and reconciled by discussion and consensus.This process continued until replicability of coding occurred across the 4 researchers, at which point the codes and coding decisions were finalized.The final version of the codebook (Appendix B in Supplemental Materials, http://links.lww.com/HC9/A644) was then applied by one researcher per transcript to the remaining transcripts.Once the coded transcripts were reconciled, code reports were generated for each code, and narrative summaries were written, which included a narrative description of the themes and sub-themes that emerged related to each code with illustrative patient quotes highlighting each theme.Lastly, posttreatment symptoms were graded by qualitative researchers using the following severity scale: Severe: bed-ridden for days/behavior completely altered and fully prohibitive from normal routine; Moderate: had to lie down or alter behavior from the norm for a (< 7 d) recovery length, challenging to daily functions but not fully prohibitive; Normal: could continue daily routine with symptom(s).We adhered to the Standards for Reporting Qualitative Research. [24]A number of steps were taken to ensure the credibility of our research findings: use of experienced interviewers; investigator triangulation (more than 1 researcher coded the data); use of an approved interview guide; audio recording and transcribing interviews; use of qualitative software to manage the coding of transcripts; use of a common, piloted codebook; use of multiple coders; use of summary writing by multiple analysts; use of more than 1 source of data (extraction of clinical data); and persistent observation (ie, process of developing and refining the codes). [25]

Patient-reported pretreatment symptom burden
Participants were asked to describe symptoms leading up to their HCC diagnosis and the degree to which symptoms interfered with daily activities (frequency of symptoms and representative quotations in Table 2).Over half (n = 16, 62%) of patients reported no symptoms before learning about their HCC diagnosis.
Among those who did report symptoms (n = 10) prior to HCC diagnosis, the most common symptoms were abdominal pain (n = 9, 35%), fatigue (n = 6, 23%), and nausea (n = 3, 12%) (Table 2).Some participants noted that the workup of a symptom (eg, abdominal pain or gas) led to their diagnosis of HCC, some were certain that symptoms were caused by liver cancer, and others expressed uncertainty about whether symptoms were attributable to liver cancer or nonliver chronic health conditions.

Patient-reported posttreatment physical symptoms
All participants (n = 26) reported at least 1 posttreatment physical symptom.A total of 30 different symptoms were described.Of these symptoms, the majority were new symptoms, although 8 patients reported one of the same symptoms before and after treatment.Representative quotations illustrating symptoms are provided in Tables 3-6, describing symptoms after TACE, TARE, SBRT, and thermal ablation.Tables list the frequency and severity of symptoms and the frequency of symptoms present prediagnosis.
Nearly three-quarters of patients reported appetite loss (n = 19, 73%).This was reported after all LRTs but was particularly common and severe after TACE.Over half of participants reported posttreatment fatigue (n = 15, 58%), although this was more common and severe among participants treated with radiationbased therapies (TARE and SBRT).Pain, most often in the abdomen, was commonly reported (n = 12, 46%), although it was generally mild to moderate in severity.Participants who received SBRT experienced discomfort related to fiducial marker placement, including one who said, "You know they did describe saying you know, 'we're going to put these markers in,' and I just didn't understand they were going to be actually you know penetrating my skin and setting these markers down" (male, BCLC-A).Participants who received laparoscopic ablation reported complications from the placement of the ablation probe, including pain and bleeding.Other common symptoms after LRTs included nausea (n = 9, 35%), weight loss (n = 6, 23%), constipation (n = 4, 15%), and vomiting (n = 4, 15%).
Participants reported that the symptoms that most impacted their daily activities or routines were diarrhea, pain, and nausea.Changes in daily activities included decreased work productivity, inability to do daily exercise routines, inability to walk or take in normal activities, and ED visits for unexpected symptoms.Changes in work routine primarily came from lifting restrictions.Participants also reported their walking was limited by physical symptoms such as nausea, fatigue, and dizziness.
Eight participants (31%) had an ED visit within 3 months of treatment, and 1 patient had 2 ED visits.Five participants (19%) had inpatient hospitalizations within 3 months of LRT for gastrointestinal bleeding I think possibly a slight bit more you know kind of a dull ache or kind of a very shallow sort of level of pain but just kind of a mental acknowledgment that there was something there.(male, BCLC-A) Well, the location on the liver where it was, was right under my diaphragm.It was a really difficult spot…and I guess that's why it was so painful.(male, BCLC-C) My side was starting to hurt again as I did activities.It was hard for me to walk for any length or period.(male, BCLC-C) Fatigue (n = 6, 23%) I started noticing that I was very, very fatigued… I had to pretty much lay down and go to sleep.And I was a very active person, did not take naps in the daytime.Well, I've been having a lot of trouble breathing… I had run for a couple of years and wasn't a bother but then all the sudden, I started having trouble breathing.(male, BCLC-D) (n = 2), HE (n = 1), PVT (n = 1), and cerebrovascular accident (n = 1).

Anticipation and management of posttreatment symptoms
Many participants emphasized a need for "balance" between getting too much information about a procedure, which may incite anxiety or fear, and having enough information to make an educated and informed treatment decision.Most participants felt like their providers did a good job with this balance, as indicated by the following statement, "I think I could have known too much, and that only gives you food to worry about.From my perspective, I think I knew just enough" (male, BCLC-C).However, when asked about aspects of treatment they would improve, several participants expressed a desire to review potential side effects in-person with a member of the oncology team rather than reviewing this information in printed patient instructions.
Participants also desired more information about how to handle symptoms in a timely manner as they were encountered.Several participants indicated that no members of the care team explained what to expect after treatment, nor did they hear from anyone to check in on them after treatment.For instance, one participant shared, "They sent me home with paperwork.He said that, "You shouldn't have much pain with this.You can take Tylenol for what you do have."And it was, "Don't be calling up here asking me for pain medicine," is the way I took it.Which I wouldn't anyway because I don't want to take pain medication.But as far as not having an appetite and vomiting, there was no instruction on that" (female, BCLC-C).
Some participants contacted care team members through electronic medical record messaging or telephone calls due to new or worsening symptoms.This contact was often prompted by a lack of understanding about whether the care team would contact the patient directly.For instance, one participant stated, "Well, I've read through some of the stuff, and I was under the impression that someone from up there would contact me like a couple weeks after the procedure" (male, BCLC-A).
Some participants mentioned seeking information on the internet about potential side effects and general information about liver cancer, which often increased distress.For instance, "I want to say it was that morning, that Sunday morning I Googled that.That Monday I called and I wanted to talk to [provider]   (Normal) (male, BCLC-A) a Side Effect Severity Grade: Normal: could continue daily routine with symptom(s); Moderate: had to lie down or alter behavior from the norm for a (< 7 d) recovery length, challenging to daily functions but not fully prohibitive; Severe: bed-ridden for days/behavior completely altered and fully prohibitive from normal routine.b Frequency of symptoms listed in order from most to least often mentioned.Abbreviations: BCLC, Barcelona Clinic Liver Cancer; TARE, transarterial radioembolization.
Patients described several ways in which they attempted to remedy their symptoms, such as taking medications including lactulose and rifaximin for fatigue, antiemetics for nausea, and analgesics (acetaminophen and oxycodone) for pain.Oral cannabidiol and smoking marijuana were used by 2 participants to address nausea, pain, and indigestion.

Interest in electronic symptom monitoring using PRO instruments
Based on a description provided by the interviewers, participants were asked about their initial impressions of electronic symptom monitoring.Representative quotes are depicted in Table 7.Most participants (20/26, 77%) stated that there could be potential benefits in an electronic symptom monitoring system.Participants discussed several potential benefits of soliciting posttreatment symptoms through electronic surveys, including the potential to heighten their team's awareness of new or worsening symptoms, improved patient-provider communication, and the ability to track symptoms over time.
Potential limitations or downsides included concern that the electronic surveys would be unnecessary if treatment was uncomplicated, that surveys would be too general and not specific enough for individual patients, and concern about the mental burden placed on patients required to complete the surveys.Furthermore, some patients stated that surveys may be unnecessary since they had no problems calling their care team to report symptoms.
Most (n = 18, 69%) participants were in favor of an online tool that would allow them to fill out electronic PRO surveys using a smartphone or electronic device (eg, laptop).Some patients (n = 6, 23%) expressed a preference for telephone-based symptom monitoring due to a lack of computer literacy or access to a smartphone or computer.Most patients (n = 21, 81%) were confident they could complete symptom questionnaires without assistance.Regarding the frequency of completing surveys, there were a range of patient responses, including willingness to submit weekly, biweekly, or monthly electronic surveys.Other participants suggested that the frequency should be flexible and depend on factors such as time to accommodate variability in posttreatment symptom timing and severity.

DISCUSSION
Using qualitative research methods to elicit patients' experiences in their own words, this qualitative study of patients with HCC recently receiving LRTs demonstrates that while pre-HCC diagnosis symptoms are reported by a minority of patients, posttreatment symptoms are universal and lead to a variety of impairments in daily activities and functioning.Posttreatment symptoms result in increased health care utilization, with nearly one-third of participants requiring an ED visit within 3 months of undergoing treatment.Patients described diarrhea, pain, and nausea as symptoms that interfered most with daily activities and functioning.Interference with daily activities and the frequency of posttreatment health care utilization demonstrates the impact these symptoms have on their lives and highlights opportunities to enhance patientcentered care.Participants expressed interest in electronic symptom monitoring, with the majority preferring a web-based format and completing surveys weekly or biweekly.These findings suggest that electronic symptom monitoring in patients after HCC treatment may be an acceptable means to proactively address patientreported symptoms.A symptom monitoring system may have the capacity to improve patients' functioning and quality of life after LRT treatment and reduce health care utilization.
Unlike prior qualitative studies in HCC, our study includes perspectives from patients who have received SBRT, PRO data collected on average 3 weeks after LRT treatment, and specifically evaluated patient perspectives on the role of electronic symptom monitoring.Our study adds several unique aspects to this literature, including elucidation of novel symptoms not highlighted in prior work (eg, nausea, constipation, loss of taste, weight loss, and pain/swelling/bleeding from wounds).

Patient-reported symptoms to inform selection of PROs most relevant to patients' quality of life
Our findings have the potential to improve HCC care in several ways.A better understanding of posttreatment patient-reported symptoms will ensure the selection of PRO measures that quantify symptoms, most importantly from the patient's perspective.28][29][30] Future comparative effectiveness and toxicity studies among patients receiving LRT that incorporate appropriate PROs will directly inform patient-provider communication and resulting treatment decisions.In a large survey study, most patients with HCC preferred treatments that maximized overall survival but were willing to accept tradeoffs in survival to avoid treatmentrelated side effects. [31]This may be particularly relevant for noncurative LRT options, which often have similar effects on overall survival but distinct side effect profiles.Thus, real-world data incorporating relevant PROs will inform decisions for patients and clinicians.a Side Effect Severity Grade: Normal: could continue daily routine with symptom(s); Moderate: had to lie down or alter behavior from the norm for a ( < 7 d) recovery length, challenging to daily functions but not fully prohibitive; Severe: bed-ridden for days/behavior completely altered and fully prohibitive from normal routine.b Frequency of symptoms listed in order from most to least often mentioned.Abbreviations: BCLC, Barcelona Clinic Liver Cancer; SBRT, stereotactic body radiation therapy.
Need for HCC-specific PRO instruments among early/intermediate-stage patients with HCC It is not clear which PRO instrument or combination of instruments is best equipped to monitor disease-related or treatment-related symptoms in HCC, although there is emerging guidance in cirrhosis. [32]There are several PRO instruments that have been empirically validated that could be used to monitor HCC-related or treatmentrelated symptoms in this population. [12]Generic instruments, such as the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire -C30, [33] Short Form 36, [34] or Short Form -8, have been empirically validated but currently lack content validity for patients specifically living with HCC.Disease or treatment-related symptoms may be more thoroughly assessed by disease-specific instruments, such as the EORTC quality of life questionnaire-HCC-18, [35]   Functional Assessment of Chronic Illness TherapyHepatobiliary, [36] or the Functional Assessment of Chronic Illness Therapy Hepatobiliary Symptom Index-8. [37]The Hepatobiliary Symptom Index-8 demonstrated good psychometric properties among patients with HCC [37] and has established meaningful change scores [30,38] but may not include all relevant symptoms for patients with localized HCC who have received LRTs.The Patient-Reported Outcomes Measurement Information System Profile-29 instrument has recently demonstrated validity and efficiency for assessing HRQOL in patients with chronic liver disease. [39]Specific items from the cancer-specific Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events may capture additional symptoms and treatment side effects, but more content and empirical validation are needed.The findings of our study support the need to develop new PROs specific to patients with HCC receiving LRTs.To maximize the clinical impact of any posttreatment PRO instrument, it will be important to balance the need to capture all symptoms meaningful to patients while avoiding excessive burden of patients and providers that would limit its uptake in real-world practice.

Role of proactive symptom monitoring in HCC
Proactive symptom monitoring with electronic PRO surveys has the potential to facilitate the early identification of symptoms that can be addressed by clinicians.[16] While these potential benefits are remarkable, it will be important to determine if these findings translate to localized HCC.Patients with localized HCC are distinct from those with metastatic cancers in several ways, including the presence of underlying cirrhosis, which contributes to symptoms, and less frequent contact with patients after LRTs compared to those on systemic therapy.Therefore, it is possible that patients with intermediate-stage HCC may experience larger benefits from electronic symptom monitoring.Findings from our study suggest that an electronic symptom monitoring tool has potential appeal for patients with HCC; however, the range of responses we elicited suggests the need for multiple modality options based on individual patient's comfort level, access to internet-based technology, and need for assistance.
Furthermore, there is a need for customization to implement PROs into clinical practice.A recent concise review outlines several important factors in the process of PRO collection within clinical hepatology, including clinician training, monitoring systems to track PRO collection (eg, with integration in the electronic medical record ), and the importance of a physician champion. [40]uture research is needed to assess when and how best to implement PROs in hepatology care and evaluate how they influence clinical care.

Alternative strategies to address symptoms in HCC
Proactive symptom monitoring with electronic PRO instruments is just one of many potential strategies to address symptom burden in patients with HCC.A recent AASLD guidance provides an overview of palliative care and symptom-based management strategies for patients with decompensated cirrhosis. [41]here are a number of studies demonstrating symptom burden and HRQOL can be improved in patients with decompensated cirrhosis [42][43][44] and cancer [45][46][47] through a number of palliative care interventions including nurse-led, psychologist-led, social worker-led, or physician-led symptom assessments, care coordination interventions, self-management interventions, and mindfulness-based stress reduction.Recently, a single-center pilot trial among patients with HCC demonstrated that visits with a palliative care provider resulted in improvements in HRQOL and symptoms. [48]

Potential limitations
Our study is strengthened by a comprehensive qualitative assessment of posttreatment symptoms among patients with HCC who recently received LRT.However, it is important to consider its potential limitations.First, this is a single-center study limited to Englishspeakers who were mostly White and non-Hispanic; as such, our findings may not be generalizable to non- White, non-English-speaking patients.Of note, the UNC North Carolina Basnight Cancer Hospital serves all 100 counties of NC, and our cohort included broad representation across the state.Second, while it is difficult to determine if posttreatment patient-reported symptoms are attributable to cirrhosis, HCC, other comorbidities, or the treatment itself, the pretreatment symptoms serve as a reference for comparison.Thus, change in symptoms from pretreatment to posttreatment is presumably caused by treatment, as LRT was the main intervening factor; however, other causes cannot be ruled out.Many pretreatment symptoms could be attributable to ascites, HE, medications (eg, lactulose), and non-liver-related comorbidities (eg, diabetes mellitus, obstructive sleep apnea, gastroesophageal reflux disease) (Supplemental Table S1, Supplemental Digital Content 1, http://links.lww.com/HC9/A644).Most of our cohort had well-compensated cirrhosis with a low burden of ascites and HE, reducing the likelihood that high baseline symptoms were only due to cirrhosis.Third, while our sample did include a good distribution of LRT modalities, the sample size was insufficient to make comparisons of posttreatment symptoms stratified by specific modalities.Therefore, larger comparative studies of posttreatment symptoms and HRQOL are needed for patients with HCC receiving LRTs.Lastly, this qualitative study did not provide information on how best to guide symptom monitoring, such as whether it should be universally offered or based on baseline risk factors (eg, cancer stage or Child-Pugh score) and whether it should be patientinitiated or provider-initiated.
In conclusion, this qualitative study of patients with HCC who had recently received LRTs identified many different physical symptoms that affected daily activities and often led to ED visits.By further elucidating the symptom burden of patients following LRT, this study sets the stage for the selection of PROs for future patientcentered outcomes research.Patients expressed interest in an electronic PRO monitoring system that could be used to monitor and proactively address posttreatment symptoms.Given its demonstrated benefits in patients with metastatic cancers, electronic PRO monitoring should be studied in patients with HCC.
